As one organisation alone revealed it is having to turn away at least 200 children and teenagers a year, charity bosses last night warned there could be a huge rise in the number of young people committing suicide.

It comes as new figures show suicides by mentally-ill people who are treated at home have increased tenfold in less than a decade.

The Sunday Mirror is ­campaigning to improve treatment for people of all ages who suffer mental health problems.

Two weeks ago we ­revealed that three children in every classroom – that’s around a million in total – will be hit by a mental health disorder before they leave school, but only one in four will get the help they need.

The latest shocking findings come from the charity Young Minds which surveyed councils across the UK.

Of the 51 that responded, 34 said they had slashed spending on child­ren and adolescent mental health services since the Coalition Government came to power in 2010.

At Derby City Council the cut is 41 per cent. In Norfolk, 35 per cent and in Redcar and Cleveland in the North East the cash available has been cut by 27 per cent.

Charities which used to get council funding are ­particularly hard hit. Simon Newitt of Off The Record Bristol, which gives free counselling, to the under-25s, said: “We now have to tell many young people we can’t help them... and we don’t know anywhere that can.”

Meanwhile, disturbing new data shows nearly 200 people with mental health issues killed themselves in 2009 – the last rec­orded year – up from only 18 in 2000. And mental health charities fear the numbers will increase further unless the cuts to services are stopped.

Marjorie Wallace of the mental health charity SANE, said: “It is significant that the number of ­suicides by people living in the ­community has risen alarmingly.”

In contrast, the number of ­suicides by mentally-ill patients treated in hospital more than halved from 196 in 2000 to just 84 in 2009.

Ms Wallace said: “Many people can be successfully treated in the community but there are people who need to be kept safe in a psychiatric unit for their own, and occasionally other people’s, protection.”
